I RENFORCEMENT FOUNDATION.

Application led May 8, 1923. Serial No. 637,536.

' -stucco then applied thereto, as is customary,

for texample, in' the construction of, so termed, wood-'studded stucco and plaster buildings.

Where it isnecessary to attach the reen' forcement foundation to a frame work as for. example,'in theconstruction of a building it has been impossible by prior known con` structions to embed all ofthe reenforcement members in the cementitious material and at the -Same time avoid large areas of metallic contact of the reenforcement members with the furring at the points of -attachment of the reenforcement members with the frame work, said areas readily inducing a breaking down of the slab. p

Another object of this invention is to provide for entirely embedding or incasing the oxidizable metal members of the reenforcement foundation within the cementitious slab 'and at the same time to make provision for effectively securing such members to the structural surfaces ofthe building or other construction, without in the least subjecting 'the slab to 'deteriora-tion promoting bulging and cracking thereof. For example, when the reenforcement foundation breaks because of oxidation of the metal members and becomes detached from the building frame, .there are induced bulging and cracking of the stucco or plaster. Thisinvention avoids such bulging and cracking.

Another object is to make provision for increasing the ease of attachment of the re enforcement foundation to its support..

The accompanying drawings illustrate the invention:

Fig. l0 isa longitudinal view of a still different form of thelocking member.

Referring first to Figures l, 2 and 3 of the drawings,` there is provided .a reticulated member l1 of any suitable construction. In the instance shown the member l1 is formed of crossed rods or wires 12 welded or otherwise secured to one another at their crossing points. The member 11 may be made of oxidizablefmetal since it is to be perfectly embedded in the plaster or stucco slab, which is indicated at a. Thus the reticulated member 11 will be of comparatively inexpensive construction.

rIhe member 11 is connected with a suitn able support, such as that indicated at b, by employing furring members, only one of which is indicated at 13 and which is secured at suitable intervals to the support b by suitable fasteners 14, as, for example, staples. The furring member 13 extends along one side of the reticulated member 11 and not only aids in connecting the member 11 to the. support, as will 'be made clear hereinafter, but it also properly spaces the member 11 from the support vso that, when the plaster or stucco is eing applied, said plaster or .stu'ccogwill flow entirely around the reticulated .member 11 and completely embed said member.- In order that the fur-- ringlmember 13 will properly space lthe reticulatedA member- 11 from the support, said furring member is provided at intervals therealong with ro]ections 15, prefer.

by the fasteners 14. The projections 15 extend away from the reticulated member. As shown in Figure 3, both legs of the bows shown at 1`5 are preferably inthe form of compound curves to provide a narrower portion 16 and a wider portion 17, the narrower portion closely fitting the fastener14 and the wider portion admitting of the head of the hammer used in driving the fastener.

The furring member 13 may be connected to the reticulated member l1 at intervals in any suitable manner. -In this instance the connection preferably provides for attachment ofV the reticulated member to the furring member after the furring member has been fastened to the support. In this particular instance the furring member is provided. at suitable intervals with outwardly projecting bows, only one of which 1s shown at 18, inthe drawings, projecting through one of the spaces of theA reticulated member 11 from the side-on which the furring member is positioned to the other side. Through' the bow 18 extends a locking member 19 in the form of a pin. Thel end portions of the pin are interlocked with the-member 11. Though said pin may 'be straight,it is preferablynotched or toothed, as indicated at 20, one of the notches at the intermediate portion of the pin engaging the bow 18 and other notches near the ends of the pin engaging two of the wires ofthe reticulated member 11. Such construction .of the pin prevents it from slipping out of` place before the plaster orstucco is applied.

It will be readily understood that, if the ymesh of the reticulated member be sufficiently small, a backing will not benecessary to prevent the plaster 4or stucco; from falling out of place when it is applied, but a backing, such as that indicated at 21, may bev employed and, indeed, is essential if the mesh is comparativelyllarge. J

To use the invention above described, the backing21 which may be made of paper or other suitable material, will first be secured to the support b and to -other like supports, not shown,.of the building or other structure in any suitable manner, if sai'd backing is to be employed. The furring members will be secured to'the supports upon the backing if such backing. be used. After the furring members have been secured inv place, the reticulated member will then be laid against the furring members which, accordingly, properly space the reticulated member from the backing.l Then the locking pins 19 will be interwoven with'the reticulated and furring members into place to connect the reticulated member to the furring members. When these operations have been completed, the plaster or stucco, indicated at a, may be applied by any approved method so as to completely embed the reticulated member within the stucco or plaster.-

Preferably the furring members will be constructed of metal that is practically nonoxidizable', so that they will not rust at the portions of the members 15 that project out-y side of the stucco or plaster and thus, in time, become detached from the support. The fasteners 14 also will be preferably of non-oxidizable metal.

Now referring more particularly to Figure 4, there is illustrated a reticulated member 22 of different construction than the member 11 being, in fact, what is generally termed expanded metal or metal lath. The furring member 13 is the onel previously described, but the locking pin 23 is straight, in this insta ce, with the exception of an angularly nt end 24 which engages the member 22' and, consequently, prevents vthe locking pin from falling out of place.

.vNow, referring to Figure 5` of the drawings, al furring member is indicated at-25 and is in the form of a `metal strip provided with projections or bows26 at intervals,'and the bows are perforated at 27 for v securing by nails, not shown, to a support,

not shown. The furring member is preferably provided at suitable intervals with other bows, only-one of which is indicatedat 28, projecting in a 'direction bpposite to .the bows 26. The bow 28 corresponds to the bow 18 and is for the purpose of engaging the locking pin, not shown in this view.v

In Figure 6 is illustrated a furring member, similar to Figure 5 in some respects, and f the same reference characters are employed with the addition of a prime mark to indi'- cate similar .features of construction. In

'this instance, instead of providing the bow 28 to engage the member, indicated in broken lines at 29, the furring member is provided with a tongue 30 which is partially cut and bent from the body of the furring member so as to. extend part Way around the reticulated member'29.

In the form of furring member disclosed at 31 in Figure 7, said furring member 4is provided at intervals therealong with bows,

only one of whichis shown at 32. Projecting from the bow 32 is a fastening member 33 formed by pinching together a portion of th'e furring member so as to form a more or less sharpened member that may be' driven into the support, indicated at 34..` The backing, indicated at 35 may be employed or not,

' according to the size of mesh of thereticullated member and desires of the constructor.

In Figure 8'is illustrated a still different form of furring member. 36 in the form of a Vstrip provided at suitable intervals with bows, only onerdf which is shown at 37.

Projecting from thebow 37 'isa fastening l member 38 which is formed by pinching together different portions o f the strip 36 so as to produce a more or less sharpened member that may be driven into a support. In

making' the furring member 86, a strip of metal may be' provided with longitudinally extending slits, one of Which is comparatively short adjacent the end of the strip, and the other comparatively long beginning a short distance from the rst slit. Then the end portion with the sliorte` slit will be 'bent at an angle to the remaining portion of 'shaped ends 4:1 adapted to engage the reticulated member, not shown, so as to prevent the pin becoming displaced.

` In Figure 10 the locking pin 42 is straight with the exception of its intermediate portion which is notched or bowed at 43 similar l 4to the notch 20 of the pin 19 that engages the furring member 13.

I claim: j' 1.
